THHP defines itself an organization of "concerned individuals working together to educate and inform about the Holocaust." Some of the members remain anonymous. The founding director was Harry W. Mazal, OBE, who died in 2011.

More than 20 "short essays" address a variety of questions of interest, including an extensive bibliography of Holocaust related topics. There is also a section devoted to Holocaust denial, including direct debunking of deniers such as David Irving, Ernst Zündel, and several others.

Additionally, THHP volunteers answer e-mails from thousands of students each year.
